A latex balloon at sea level and room temperature (25°C) has a volume of 2.42 L. When the balloon is released by the child holding it, it rises to a point in the atmosphere where the pressure is 70% of the pressure at sea level. The temperature at that altitude is 11 degrees cooler than at sea level. What is the volume of the balloon at that altitude?

Answer:

The answer to your question is: V2 = 1.94 l

Explanation:

Data

V1 = 2.42 l

T1 = 25°C

P1 = 1 atm

V2 = ?

T2 = 25 -11 = 14°C

P2 = 1(0.7) = 0.7 atm

Formula

P1V1/T1 = P2V2/T2

Clear V2 from the equation

V2 = P1V1T2/ P2T1

V2 = (1)((2.42)(14) / (0.7)(25)

V2 = 33.88 / 17.5

V2 = 1.94 l
